One year after the Nicoya quake, magnitude-5.9 temblor jolts Guanacaste

Exactly one year after the earthquake that struck the northwestern Nicoya Peninsula a temblor measuring magnitude-5.9 shook the province of Guanacaste at 6:29 a.m. Thursday, the University of Costa Rica’s National Seismological Network (RSN) said.

The Volcanological and Seismological Observatory of Costa Rica (Ovsicori) reported the quake as a magnitude-5.3.

The epicenter was located 19 kilometers southwest of Manzanillo in Santa Cruz. That is 60 km from the Nicoya earthquake epicenter.

The RSN report indicates the temblor was caused by the collision of Cocos and Caribbean plates.

At 10:30 a.m., Ovsicori registered 36 aftershocks with magnitudes of up to four degrees, however most of them have not been felt.

Neither the Red Cross or the Fire Department have received any reports of injuries or damage to structures due to the quake.

On Thursday, President Laura Chinchilla and other government officials presented a report of all the actions taken by her administration on the first anniversary of the magnitude-7.6 earthquake. It jolted most of the country starting at 8:42 a.m. and lasted some 45 seconds. A 51-year-old woman died of a heart attack following the event, although she was not included in the official quake death toll.

According to official figures, the cost of infrastructure replacement was estimated at $100 million, $20 million corresponding to repairs to the Monseñor Sanabria Hospital in the Pacific province of Puntarenas.
